AB  - The effect of carbohydrate (CHO) consumption on mood is much debated, with 
      researchers reporting both mood improvements and decrements following CHO 
      ingestion. As global consumption of sugar-sweetened products has sharply 
      increased in recent years, examining the validity of claims of an association 
      between CHOs and mood is of high importance. We conducted a systematic review and 
      meta-analysis to evaluate the relationship between acute CHO ingestion and mood. 
      We examined the time-course of CHO-mood interactions and considered the role of 
      moderator variables potentially affecting the CHO-mood relationship. Analysis of 
      176 effect sizes (31 studies, 1259 participants) revealed no positive effect of 
      CHOs on any aspect of mood at any time-point following their consumption. 
      However, CHO administration was associated with higher levels of fatigue and less 
      alertness compared with placebo within the first hour post-ingestion. These 
      findings challenge the idea that CHOs can improve mood, and might be used to 
      increase the public's awareness that the 'sugar rush' is a myth, inform health 
      policies to decrease sugar consumption, and promote healthier alternatives.
